From this table some general rules about stereo audio switching can be obtained:
• a left to both or right to both source will override any destination feature .
• a normal source will be overridden by the output feature.
• a normal destination will be overridden by the source feature.
• a mono destination will override a normal or swapped source.
• a swapped source and a swapped destination will result in a normal
crosspoint.
These features are stored on a source and destination basis in the database for
each stereo analogue audio level configured . Each crosspoint is sent together with
three extra audio bits to specify the appropriate feature.
More information is given in Part 2 of this manual.
